29-Inch Wheel (29ers)

We've heard it all before: 'This bike's for going fast, that one's for having fun.' 'This one pedals well, that one shreds.' Why not make one bike that does everything well? Well, we did, and it's called the S-Works Stumpjumper. Unrivaled handling and stiffness, sublime suspension kinematics, and a complete abandon of proprietary nonsense—it rides like a dream. And with 29-inch wheels, you're free to climb and descend at the hyper speed that 29ers are known for.
Our design goal for the new Stumpjumper was simple—build the ultimate trail bike, one that feels telepathic. And it turns out that this feeling all comes down to stiffness. Think of it this way: when the frame's telling your hands one thing and your feet another, your brain gets confused with the imbalance and the bike feels unstable. In order to fix this, we had to get to work on dialing-in the materials, shapes, and the layout.
We started by creating our own mountain-specific stiffness test, and then we looked at the layout with Finite Element Analysis (FEA) to see where we could get the biggest stiffness improvements. This led to a big discovery: The Large and X-Large frames needed more front-end stiffness while the Smalls and Mediums were just fine. We were able to create a frame design that was 20% more efficient. And in the end, this proved to be one of the lightest trail frames on the market, today.
When designing the frame with the stiffness targets being a main goal, we developed a radical new sidearm design. The front-end and rear-end are connected at three points, and the sidearm helps keep all these points super stiff and connected, all while taking about 100 grams out of the rear-end. More explicitly, this minimizes frame flex when the rear suspension is active.
We continued down the suspension path with a custom Rx Trail Tune on both the fork and rear shock. Suspension performance is highly dependent on frame, wheel, and rider size, so we use our Rx Tune to get each bike to land in the middle of the adjustment spectrum, and this gives you the biggest possible range to fine-tune your ride. Another focal point of the tune was matching the suspension characteristics between wheel sizes—we developed a specific Rx Tune for each platform. So, no matter what wheel size you prefer, you'll get perfectly linear suspension.
Steps were also taken to make this bike easy to live with. Threaded bottom brackets make a triumphant return, and we made room for up to a 3.0' tire. You're also free to run whatever aftermarket rear shock you want since we're using standard metric shocks. We revamped the SWAT box, too, making it sleeker, lighter, and with more volume. And customization is furthered with a Flip Chip that lets you to dial-in your Stumpy to your riding style. Switch it from High to Low and it drops your bottom bracket 6mm and slackens the head tube by half-a-degree. Little details also jump out to surprise you, like a newly designed ribbed chainstay protector that makes chain slap a thing of the past and nearly silences the drivetrain. Lastly, we seriously couldn't make cable routing any easier on carbon models. Full tubes can be found throughout the carbon frame, so all you have to do is push the cable and it'll come out the other end. No more lazy loop, hidden stashes of magnets, pokey spokes, or pillows to cry in.
As with every S-Works build, this S-Works Stumpjumper 29 comes with only top-of-the-line parts, like a full SRAM XX1 Eagle drivetrain, SRAM Guide RSC disc brakes, FOX Factory front and rear suspension (150/140mm respectively), and the best carbon wheels money can buy, the Roval Traverse SL 29.
- The Stumpjumper's asymmetrical, S-Works FACT 11m carbon fiber construction is lightweight, stiff, and ready to take on the trail. It's built off our 29 Trail Geometry, so it's just the right amount of both capable and comfortable. And with SWAT integration in the down tube, a threaded BB, easy cable routing, and an all-new chain silencer, it's ready for anything the trail, or you, throw at it.
- FOX FLOAT DPX2 Factory has three modes—Open, Trail, and Firm—that control large compression adjustments on-the-fly. There's also a tool to adjust compression adjustment that allows for fine-tuning of the compression in Open mode.
- The legendary FIT4 damper, large stanchions, buttery-smooth Kashima coating—the FOX 36 Factory 150mm fork is one of the best out there.

With our new S-Works Enduro 29/6Fattie, some people asked us, "Why mess with a good thing?" But where some would comfortably rest on their laurels, we aimed to keep evolving. And the result is the most fun you'll ever have on a mountain bike. Seriously.
We gave it a geometry that features a slacker front end, a longer top tube, short chainstays, and a lower bottom bracket. All of this together makes the bike truly feel glued to the ground, and the platform is more responsive and capable then ever. We even added some bits, like integrated storage with a SWAT Door at the down tube, and made "old" new again by making a triumphant return to a threaded bottom bracket. To keep the weight down, the frame is constructed from our top-tier FACT IS-X 11m carbon fiber. And to ensure top-level performance on the descents, this material choice is greeted by 160mm of plush rear and 160mm front travel, plus a geometry that can be "adjusted" via a shock extension with a "low/high" setting.
And handling suspension duties out back is the revolutionary Öhlins single-tube rear shock. For the build, this Enduro spares no expense at hitting the pinnacle of performance, with a full SRAM XX1 Eagle 12-speed groupset, powerful Guide RSC Carbon brakes, hand-built carbon Roval wheels, and our Command Post IRcc Wu dropper post.
- The frame's FACT IS-X 11m carbon fiber construction stands as the pinnacle of lightweight, efficient, and tough trail performance. It's been built off our 29 Geometry in order to provide an aggressive, well-rounded ride. And with internal Command Post IR routing, a return to a threaded bottom bracket, and an integrated SWAT™ Door at the down tube, you get a bike that's clean, dependable, and ready for anything that the trail has to offer.
- Featuring a three-chamber air spring and TTX (Twin Tube) damping, the Ohlins RXF 36 fork perfectly mates stiffness with a plush, responsive ride quality, and stays smooth and high in the travel without compromising bump absorption, traction, or stability. It also features high-/low-speed and rebound adjustments, and sports 160mm of plush travel.
- The one-by drivetrain is controlled by SRAM's venerable XX1 Eagle components. The system forms the ultimate in efficiency and intuitive feel, while also having the added benefit of significant weight savings and minimal required maintenance.

It's undeniable that hardtails still play an extremely important role in XC racing. So what to do? Specialized put their XC offerings on a diet, went back to the drawing board, and created the lightest damn mountain bike they've ever made—the S-Works Epic Hardtail. To provide the optimal blend of stiffness, crazy light weight, and strength, Specialized constructed the frame from their FACT 12m carbon fiber. And with its new XC 29 Geometry, the Epic is guaranteed to deliver uncompromising, blistering speed and agile handling come race day—no matter the course. The revolutionary Shimano XTR Di2 11-speed drivetrain provides unparalleled shifting precision, reliability, and accuracy, making it the secret weapon in any racer's arsenal. Shimano XTR hydraulic brakes, S-Works carbon components, and a carbon-railed saddle round out this amazing machine that will be primary weapon in your pursuit of speed.

When only the best will do, you need the ultimate trail bike. In other words, you need the S-Works Stumpjumper 29/6Fattie. It reflects everything that we've learned over the years, and in our eyes, represents the pinnacle of trail performance.
Starting at the carbon layup, it features our highest-end FACT 11m for an ultra-lightweight, strong, and stiff construction. The carbon molding process also allowed us to revolutionize how you carry your trail essentials with the SWAT Door found at the down tube. This compartment will fit a tube, a tool, and pump without rattling or compromising the structural integrity of the frame.
You'll also find an aggressive, trail-eating geometry that features ridiculously short chainstays, a roomy top tube, a low bottom bracket, a slacked out front end, and our proprietary Rx Trail Tune at the rear shock. This frame also includes a custom Ohlins STX rear shock with our venerable, easy-to-set-up AUTOSAG system. This Stumpy's design also allows you the opportunity to toggle between 29-inch wheels and 6Fattie wheels (not included), allowing for the ultimate in configuration options for the trail at hand.
- FACT 11m carbon fiber Trail Chassis with Stumpjumper FSR full carbon rear end blends stiffness with light weight to form the pinnacle of efficiency, while fully enclosed cable routing and an integrated SWAT Door create exceptional handling and zero-hassle storage.
- The custom Ohlins STX single-tube air shock at the rear features high- and low-speed compression, as well as low-speed rebound. You'll also find an extra-volume reservoir that allows for more oil, which results in more control and an ultra-plush ride quality.

Call it a healthy disrespect for the status quo, but Specialized was getting bored with traditional hardtail designs. So instead of playing along, they opted to turn the cross country world on its head with a bike that's not only the lightest mountain frame they've ever made, it's their lightest frame—period. Introducing the S-Works Epic Hardtail World Cup. To provide the optimal blend of stiffness, crazy light weight, and strength, Specialized constructed the frame from their FACT 12m carbon fiber, and when combined with the XC 29 Geometry, the Epic frame is guaranteed to deliver uncompromising, blistering speed and agile handling come race day—no matter the course. The RockShox SID World Cup 29 with Brain fork provides 90/100mm of efficient travel. It features Brain technology that distinguishes between terrain and rider input in order to maximize your power, while a Brain Fade adjusts the oil flow when not hitting bumps. The one-by drivetrain is controlled by SRAM's venerable XX1 Eagle components to form the ultimate in efficiency and intuitive feel, while also having the added benefit of significant weight savings and minimal required maintenance. SRAM Level Ultimate hydraulic brakes, S-Works carbon components, and a carbon-railed saddle round out this amazing machine that will be primary weapon in your pursuit of speed.

You like gettin’ rowdy, we like gettin’ rowdy, so we figured, “Why not create a bike that lets us do the thing we all love most?” Well, that’s exactly what we did with the Enduro. Its fast-rolling 29-inch wheels and modern frame have been purpose-built to make short work of the rockiest, gnarliest, and steepest trails, while still climbing well enough to get you there. Witness the sickness.
Our quest was to create the perfect long-travel trail bike, and it all began with a close look at the geometry. Basically, we modernized it— slacking out the front end, lengthening the top tube, shortening the chainstays, and lowering the bottom bracket. All of this together makes the bike truly feel glued to the ground, and the platform is more responsive and capable than ever.
We then added some crucial bits to make your ride, well, better. We're talking stuff like integrated storage with a SWAT Door at the down tube, a triumphant return to a threaded bottom bracket, and internal cable routing with guides that make cabling super easy. And to keep the weight down, this S-Works frame is constructed from our top-tier FACT IS-X 11m carbon fiber. To guarantee high degrees of "shredability," this material is greeted by 160mm of plush front and rear travel, plus a geometry that can be "adjusted" via a shock extension with a "low/high" setting.

There's not much that matches the feeling of powering up a pitch on a featherweight bike, and we designed the new S-Works Epic Hardtail frame with this in mind. It's less than 900 grams, exceptionally stiff, and it features a Rider First Engineered design. It's the perfect jumping off point to begin creating your dream build.
Over the last decade, cross country racing has evolved into a completely different animal—the courses are rowdier, more technical, and overall, they're inherently different. Because of this, we realized that the best bike for the job needs to not only be lightweight and stiff but also be able to descend and climb with equal prowess. Determining the best geometry was the easier of the two, as we took our current XC race geo and added some trail DNA to the mix. This equates to a longer top tube, a shortened head tube, and a slacked-out front end, the result of which is a tremendous increase in downhill stability, plus a wider fit range. And just as importantly, this doesn't require any sacrifice of climbing proficiency. The weight aspect was more complicated, though. We were posed with the question, "How do you take weight out of something that's already so light?" But the answer was relatively obvious: you get the best mountain bike engineers together in one room and let the magic come out.
Up until now, there were two ways to lighten up a frame—use less of the same grade of carbon or use less of a higher-grade carbon. Option one is never a viable solution as it sacrifices stiffness and strength, two attributes that shouldn't be tampered with. And while we did end up using option two, we weren't content with the amount of weight we could cut out by just using a different grade of carbon. So how else do you cut weight? Well, we began looking at our layup schedules to see if they could be improved, which shed light on a new discovery—layup inefficiencies.
Beginning with our Rider-First Engineered frame technology, each size Epic Hardtail is specifically tailored to size—every carbon layup and tube are exclusively selected based upon hundreds of hours of collected ride data. What does this mean for you? It not only creates the optimal balance of rigidity, weight, and responsiveness across every frame size, but it led us to the discovery of how to save weight through the studying of the layup.
Through extensive layup studies, we made the discovery that, by further controlling the construction and layup schedules, we could drastically decrease weight, all while maintaining the ride characteristics that you'd expect from a top-level XC race bike. With this discovery, each frame now features complex cut carbon plys that allow difficult junctions to be covered with less overlap. And while this does complicate the carbon frame puzzle by adding more pieces to the mix, it allows us to design and place them more intelligently. The result of this is a lighter frame, stronger junctions, and a drastic increase in stiffness. We then took the weight savings one step further by using Japanese military ballistic-grade carbon, which we now call 12m, to create the lightest mountain bike we've ever made. How much lighter of a frame, you ask? Less than 900 grams for a size Large frame—the same weight as a full 24oz Purist water bottle.

With more World Championship titles, Olympic medals, and Cape Epic wins than you can count, the S-Works Epic frame can truly be built as the fastest XC bike on the planet. Fast and flat, rowdy and technical, punchy and hard—no matter the course, it’s the best tool to get you to the top of the podium.
Race courses have evolved over the past few years. They're more technical, steeper, and more challenging to ride. But instead of quivering in our boots, we saw this as an opportunity to make something special—something that both World Cup athletes and XC riders alike can instantly feel the benefit from. We looked at the sum of parts that make a bike handle well, like the head angle, reach, stack, chainstay length, fork offset, etc., and reevaluated all of it. Increasing the reach made a bike that was more stable at speed and generally more comfortable to ride. Dropper posts? Yep, those fit, and not just a short-travel XC option, but full-length droppers that fit in the 30.9mm seat tube. Head angle? We slacked that out, but not without evaluating the overall handling package. It now lands on a custom offset, 42mm fork that works with the slacker head angle in order to behave itself in tight corners and through switchbacks.
Next comes Brain 2.0. The original Brain changed the way the bike world looked at suspension, both in its inefficiencies and benefits alike. And oh, was it good. It won races and put a flag in the ground for us as a true leader in innovation and suspension development, but we knew that we could make it better. Simple physics told us that, by moving the Brain closer to the rear axle, it would be in the most sensitive spot. And after countless hours with the RockShox team, the Brain became more than just a slight upgrade. It's totally reborn. Now, it reacts seamlessly to bump forces, it has much more consistent damping performance, and finally, it integrates the hoses into the suspension links. This, in turn, improves oil paths, and it creates an incredibly sleek package that outperforms anything on the market.
The Epic also has a rider Rider-First Engineered design that places complex carbon pieces in all the right places, and this greatly increases stiffness in the front-end for a vast improvement in ride quality and control. To go along with this, each frame size has size-specific tubes that result in the stiffest, best riding XC bike we've ever developed—no matter the frame size.
And while stiffness, Brain technology, and geometry features are cool and all, we know what you're thinking, 'What about weight?' We're glad you asked. With the goal of the new Epic to be the fastest XC mountain bike we've ever made, weight was at the top of our priorities list. We started with an efficient frame layout and tube shapes that feature clean cable routing, integrated channels through the shock extension, straight tubes with fewer curves, and optimized torsion profiles in every section. And, if you're curious, this weight savings is equivalent to shedding a chainstay and shock extension from the previous Epic—nearly 350 grams.
This frame comes equipped with a custom RockShox Micro Brain rear shock w/ a Spike Valve. Building out the rest of that dream build is up to you—we hope to see it out on the course soon.
- S-Works FACT 12m carbon fiber frame is the best combination of stiffness, strength, and light overall weight, resulting in the utmost efficiency and speed. Meanwhile, the new geometry, RockShox Brain shock, and 100mm of travel make the Epic the best handling, fastest XC bike you've ever been on.

Ever been in the middle of stage race and needed just a little more margin for error on the descents? Or maybe you've been speeding through the backcountry and felt beat up, near bonking, and you just needed to make it back to the trailhead without going over the bars? Yeah, we’ve been there, too. And that's why we made a bike that’s perfect for those situations. Say hello to the S-Works Epic EVO—it’s, well, a more "epic" Epic.
Take a look around our office and you're going to see plenty Epics—most of them wearing dropper posts, wider tires and bars, and slightly longer forks. That's because the Epics that we're Frankensteining are not only fast off the start line, they're even better suited to masochistically long rides, multi-day stage races, and fast backcountry missions. At some point, we looked around and said to ourselves, “We should offer this bike, right out of the box, right?” So we did.
So let's dig into the details. First off, the EVO ups the fork travel from 100mm to 120mm. This gives you some relief up front while also slacking-out the front-end by one-degree to 68.5º. Next up, we added a zero-offset dropper post to give you more control on descents, but this design keeps your saddle over the BB on steep climbs. We also put some meat on the tires with a grippy 2.3" Ground Control at the front and a stiffer Fast Trak at the rear with GRID protection at the sidewalls.
The Epic EVO also features our Brain 2.0. The OG Brain changed the way the bike world looked at suspension, and oh was it good. It won races and put a flag in the ground for us as a true leader in innovation and suspension development, but we knew that we could make it better. Simple physics told us that, by moving the Brain closer to the rear axle, it would be in the most sensitive spot. And after some lengthy R&D, it's totally new. Now, it reacts seamlessly to bump forces, it has much more consistent damping performance, and finally, it integrates the hoses into the suspension links. This means that the oil paths are improved, and that creates an incredibly sleek package that outperforms anything on the market.
This is also among our first Rider-First Engineered MTB frames, where the tubes place complex carbon pieces in all the right places, regardless of the frame size. As a result, stiffness is increased in the front-end for a vast improvement in the ride and in control. And to go along with this, each frame size has size-specific tubes that result in the stiffest, best-riding XC bike we've ever developed.
And while stiffness, Brain technology, and geometry features are cool and all, we know what you’re thinking, "What about the weight?” We’re glad you asked. The weight-savings on the frame is equivalent to shedding a chainstay and shock extension from the previous Epic—nearly 525 grams. And now, carbon models also feature additional tire clearance to accommodate wider, 2.3-inch tires. More traction, ultimately, equals more speed.
The build of this S-Works Epic EVO spares no expense, featuring Shimano’s new 12-speed XTR groupset and brakes, a FOX Factory Step-Cast 34 fork, and a hand-built Roval Control SL carbon wheelset.
- A FOX Factory Step-Cast 34 handles suspension duties up front with 120mm of plush travel. The Fit4 damper provides plenty of adjustability, while the new Step-Cast design keeps weight at a minimum while boosting stiffness.
- The Roval Control SL carbon wheels are the ultimate XC wheelset. They feature a 25mm internal width for low rolling resistance, a strong, hookless bead rim construction, and an ultra-low weight of only 1320 grams.
- A dropper post on an XC bike? Yeah, you can thank us later. Adding minimal weight, but tons of shredability, the FOX Factory Transfer dropper post, with zero-offset, keeps your position over the bottom bracket and it gets out of the way while you're descending.

Fast and flat, rowdy and technical, punchy and hard—no matter the course, the S-Works Epic with SRAM XX1 Eagle is the best tool to get you to the top of the podium. Its design is all-new, and boy, oh boy is it fast.
Race courses have evolved over the past few years. They're more technical, steeper, and simply more challenging to ride. But instead of quivering in our boots, we saw this as an opportunity to make something special—something that both World Cup athletes and XC riders alike can instantly feel the benefit from. We looked at the sum of parts that make a bike handle well, like the head angle, reach, stack, chainstay length, fork offset, etc., and reevaluated all of it. Increasing the reach made a bike that was more stable at speed and generally more comfortable to ride. Dropper posts? Yep, those fit, and not just a short- travel XC option, but full-length droppers that fit in the 30.9mm seat tube. Head angle? We slacked that out, but not without evaluating the overall handling package. It now lands on a custom offset, 42mm fork that works with the slacker head angle in order to behave itself in tight corners and through switchbacks.
Next comes the redesigned Brain technology, Brain 2.0. The Brain changed the way the bike world looked at suspension, both its inefficiencies and benefits alike. And oh was it good. It won races and put a flag in the ground for us as a true leader in innovation and suspension development, but we knew that we could make it better. Simple physics told us that, by moving the Brain closer to the rear axle, it would be in the most sensitive spot. And after countless hours with the RockShox team, the new Brain became more than just a slight upgrade. It's totally new. Now, it reacts seamlessly to bump forces, it has much more consistent damping performance, and finally, it integrates the hoses into the suspension links. This, in turn, improves oil paths, and it creates an incredibly sleek package that outperforms anything on the market.
The new Epic also gets a serious upgrade in the stiffness department. The Rider-First Engineered tubes place complex carbon pieces in all the right places, which greatly increases stiffness in the front end for a vast improvement in ride quality and control. To go along with this, each frame size has size- specific tubes that result in the stiffest, best riding XC bike we've ever developed — no matter the frame size.
And while stiffness, Brain technology, and geometry features are cool and all, we know what you're thinking, "What about weight?" We're glad you asked. With the goal of the new Epic to be the fastest XC mountain bike we've ever made, weight was at the top of our priorities list. We started with an efficient frame layout and tube shapes that feature clean cable routing, integrated channels through the shock extension, straight tubes with less curves, and optimized torsion profiles in every section. And, if you're curious, this weight savings is equivalent to shedding a chainstay and shock extension from the previous Epic — nearly 350 grams.
For this S-Works model, we spared no expense with the build, so it features a custom RockShox SID World Cup fork, a 12-speed SRAM XX1 Eagle groupset, powerful SRAM Level Ultimate brakes, and hand-built, featherweight Roval Control SL wheels.
- S-Works FACT 12m carbon fiber frame is the best combination of stiffness, strength, and light overall weight, resulting in the utmost efficiency and speed. Meanwhile, the new geometry, RockShox Brain shock, and 100mm of travel, make the Epic the best handling, fastest XC bike you've ever been on.
- Our custom RockShox SID WC fork with Brain features a full-carbon upper, top-adjust Brain fade, and a custom offset, making it the perfect match to the new Epic.
- SRAM XX1 Eagle bits handle the shifting duties, providing a wide range of useable gears that make climbing and descending equally doable.
